Application :Bled April 8, 1927. Serial No. 182,165.

The present invention relates to improvements in a brake for use upon motor vehicles and has for its principal object to provide a brake which is of' such construction as to at all times be positive and eiicient in its braking action. y

One of the important objects of the present invention is to provide a. vehicle brake wherein an annular braking block is supported in adapted to the numerals are employed to designate like parts throughout the same: Figure 1 is a side elevation of a vehicle brake embodying my invention,

Fi ure 2 is as sectional View taken approximate y on the line 2f-2 of Figure 1, and` Figure 3 is a similar section taken on the line 3 3 of Figure 1.

In the drawing, whencefor the purpose of illustration is shown the preferred embodiment of 4my invention, the numeral 1 designates the brake drum and supported on the outer peripheral lface of this drum is the channel shaped brake shoe 2. A series of inwardly extending fingers or lugs are formed on `one side of the channel shaped shoe 2 and these lugs are secured to the side of the drum, by'any appropriate fastening means such as is shown at 4. In this man-f ner, the channel shaped shoe will be rigidly secured on the drum for'rotation therewith.

The brake block '.5 forming thesalient feature of the present invention 4is in theform of an annulus and is supported within the l' channel shaped shoe 2. Securing bolts 6 xtend transversely-through the sides ofthe channel shaped shoe 2 and the intermediate portion of the annular lblock 5 in the 'Inanner clearly shown in Figure 3.

The outer peripheral portion of the brake block 5 projectsbe-yond the outer-edges'of the sides of the Achannel shaped shoe 2 and' this is clearly illustrated in the several ffig,- ures of the drawing. This brake block is preferably formed of abrown compact variety of asbestos, resembling fossil wood and known as rock wood and I provide a brake member of this particular material, the same will be strong'and durable and furthermore will' prevent slippage ofl the brakev band around the outer peripheral face of the an- -PATENT oFFlCE.'

nular brake block' 5 whenlthe brake is apl plied. v.

'The brake band is shown at 7 and the brake lining is secured to the inner face thereof as indicated at 8. This' brake band and lining is of conventional construction, the brakel band being split and the usual `attracting means designated by the numeral 9 is prof vided whereby' the ends of the brake y'band may be contracted for applying the brake in a manner well known in the art.

While I have shown the preferred embodiment of my invention, it is to be understood vthat varip-us changes inl size, shape andarrangement of parts maybe resorted to without departing from the spirit or sacrificing any of the advantages of the appended claims.

What I claim is:

1. In a vehicle brake, a shoe, a drum, a channel shaped shoe encircling the drum, inwardlyextending lugs formed on the channel shaped shoe and secured to the side of the drum, an annular brake block arranged within the shoe, the outer eripheral portion of the block projecting beyond the' outer edges of the sides of the channel shaped shoe,

and. securing bolts extending transversely through the sides of the shoe and said block.

2. In a vehicle brake, a shoe, a druIn,- channel shapedyshoe encircling the drum, in.- wardly extending lugs formedon the cha-nthe-drum, an annular-brake block arranged Awithin the shoe, the outer peripheral portion nel shapedshoe tand secured to the -side of v of` the block projecting beyond the outer edges bf the sides of the channel shaped shoe,
